Ask about warranty coverage when you call, too. Fluid is the lifeblood of an automatic. It carries heat away, lubricates gears and bearings and provides the hydraulic pressure that makes shifts happen. It also wears out. Fluid service is the routine job that keeps that from turning into a larger repair. ## Why fluid ages Automatic transmission fluid is a mix of base oil and additives that control friction, resist foaming and protect metal. Heat breaks those additives down, and wear leaves tiny particles that circulate until the filter or magnet catches them. When fluid is old, shifts can get rough, the transmission runs hotter and parts wear faster. Heat from summer driving, towing and stop-and-go use speeds all of this up. ## How often? Your owner's manual gives the maker's interval, and it differs between vehicles and between normal and severe use. The Car Care Council says: "For longest automatic transmission life, have the fluid and filter changed every 24,000 to 36,000 miles." Manuals for vehicles that tow, haul or drive in heat often list a shorter interval for severe service, and some list none at all. Read the [fluid change interval guide](https://a1transmissionrenonv.com/guides/transmission-fluid-change-interval/) for how to find yours. ## Which fluid goes in Fluid is not one size fits all. Automatic transmissions are designed around specific fluids, and the wrong one can change how the clutches grip. The [transmission fluid types guide](https://a1transmissionrenonv.com/guides/transmission-fluid-types/) explains the labels. Give the shop your year, make, model and engine and it will tell you what applies to your vehicle. ## How the shop approaches it The shop calls it fluid service, and the exact procedure for your vehicle is something to ask about when you call. As with all of its work, it looks first: fluid level, color, smell and any leaks. Dark, burnt-smelling fluid or metal in the pan is information the mechanic shares with you. A fluid service is also not a cure for a transmission that already has internal damage, which is why the diagnosis comes first. ## When fluid is the symptom Fluid trouble shows up as [a burning smell](https://a1transmissionrenonv.com/symptoms/burning-smell/), [overheating](https://a1transmissionrenonv.com/symptoms/overheating/), [hard or late shifting](https://a1transmissionrenonv.com/symptoms/harsh-or-late-shifting/) and [red or brown fluid on the ground](https://a1transmissionrenonv.com/symptoms/fluid-leak/). If you can safely check the level yourself, the guide on [how to check transmission fluid](https://a1transmissionrenonv.com/guides/how-to-check-transmission-fluid/) walks through it. Ask about warranty coverage and cost when you call. ### Sources - [Car Care Council, Be Car Care Aware](https://www.carcare.org/) - [Automatic transmission fluid, Wikipedia](https://en.wikipedia.org/wiki/Automatic_transmission_fluid) - [Automatic transmission, Wikipedia](https://en.wikipedia.org/wiki/Automatic_transmission) Keep reading ## Related pages [How often to change transmission fluid How often to change transmission fluid is set by your vehicle's maker and printed in the owner's manual, and it is shorter if you tow, haul.](https://a1transmissionrenonv.com/guides/transmission-fluid-change-interval/)[Transmission fluid color: what it tells you Transmission fluid color tells you roughly how old the fluid is and whether the transmission has been running hot: bright red or green is normal.](https://a1transmissionrenonv.com/guides/transmission-fluid-color/)[Transmission fluid types (ATF) explained Automatic transmission fluid (ATF) comes in several specifications set by vehicle makers, and the right one is the one named in your owner's manual.](https://a1transmissionrenonv.com/guides/transmission-fluid-types/)[Transmission diagnosis Transmission diagnosis is the step where a mechanic finds out what is actually wrong before choosing a repair.](https://a1transmissionrenonv.com/services/transmission-diagnosis/) Inside the shop ## The shop at 670 East Grove Street Google reviews ## What drivers say 4.6 ★★★★ ★ [112 Google reviews (read October 18, 2026)](https://maps.google.com/maps?cid=809418658926218921) ★★★★★ A-1 Transmission is my go to Transmission shop.

Call [(775) 829-1333](tel:+17758291333) during shop hours. More answers are on the [questions page](https://a1transmissionrenonv.com/faq/). ### How do I know if my transmission needs fluid service? Check your owner's manual interval first. Dark or burnt-smelling fluid, rough shifts and a rising temperature are other reasons to call. ### Will fluid service fix a slipping transmission? Sometimes slipping is caused by low or worn fluid, and sometimes by internal wear that fluid cannot reverse. The shop looks and tells you which. ### Do manual transmissions and transfer cases need fluid service? Both run in lubricant that wears out. Your owner's manual lists the interval and the shop can advise for your vehicle. ### Do I need an appointment for fluid service? Appointments are suggested, and walk-ins are welcome during business hours. Call (775) 829-1333 to ask.
